This is an OpenPGP signature for that mail. To verify it, switch from using a Webmail-Frontend to a mail program supporting OpenPGP. I recommend Thunderbird plus Enigmail. In Webfrontents you'll never be able to verify signatures nore to read or write encrypted mails. (I also suggest not using gmail, yahoo or that like, but this is a different topic.) -- Schönen Gruß Hartmut Goebel Dipl.-Informatiker (univ), CISSP, CSSLP Information Security Management, Security Governance, Secure Software Development Goebel Consult, Landshut http://www.goebel-consult.de Blog: http://www.goebel-consult.de/blog/1.-platz-bei-google-ganz-ohne-seo Kolumne: http://www.cissp-gefluester.de/2012-02-bring-your-own-life-glosse Goebel Consult ist Mitglied bei http://www.7-it.de/
